摘要
针对交联聚乙烯绝缘海底电缆在我国海洋风电的应用情况,首先介绍了中压交流海底电缆在海洋风电中的示范性应用,概述了三芯高压交流海缆的技术性突破及电压等级由35 kV向110 kV和220 kV发展过程中的结构改进和性能升级情况,对比分析了三芯海缆与单芯海缆制造成本的差异,并简述了柔性直流海缆的产品特点和绝缘结构设计方法。最后结合未来海洋风电向大容量、远海建设的趋势,提出了交联聚乙烯绝缘海底电缆应用比重向湿式结构阵列海缆和高压柔性直流海缆发展的展望。
Aiming at the application situation of XLPE insulated submarine cable in the field of China＇s offshore wind power,firstly the typical applications of mid-voltage AC submarine cable to offshore wind farms are summarized. The technical breakthrough of three-core HVAC submarine cable,the structure improvement and performance upgrade in the developing process of cable voltage level from 35 kV to 110 kV and 220 kV are introduced. Fabricating costs are compared between three-core and one-core submarine cables.Then the product features and insulation structure design method of VSC-HVDC submarine cable are briefed. Finally,according to the trend of large capacity and high seas construction for future offshore wind farm,it is proposed that the application of XLPE insulated submarine cable should focus on wet type structure array submarine cable and VSC-HVDC submarine cable in the future.
